The Sixth Embodiment

An antiseismic supporting base body 100 e of the present invention is shown in FIG. 8. The elements of this embodiment illustrated in this Fig. are similar to those in the fourth embodiment. So the same element of both embodiments is indicated with same symbol. The sixth embodiment is different from the fourth embodiment in as follows. In this embodiment, an ancillary bearing 2111 e, an ancillary bearing 2121 e, and an ancillary bearing 2141 e are provided at the bottom of the main pile 211 e, the bottom of the subsidiary pile 212 e, and the bottom of the ancillary pile 214 e respectively. The shape of the ancillary bearing 2111 e, 2121 e, 2141 e are similar to an inverted cone or to an inverted pyramid.

The friction between the antiseismic body 21 e of the antiseismic supporting base body 100 e and the stratum increases, and the ability of the antiseismic body 21 e to bear the load and the stress resulted form the load raises.

The surface area of the external surface of the antiseismic body of the antiseismic supporting base body is decreased continuously or discontinuously from top to bottom, and the strongest antiseismic strength of the antiseismic body is located in the central axis of the antiseismic body, so that the antiseismic supporting base body in this present disclosure has advantages as follows:

(1) When the earthquake happens, the earthquake wave from the seismic source underground radiates to the ground. And while this earthquake wave is attacking the antiseismic supporting base body mentioned above, because the shape of the antiseismic body is similar to an inverted cone or to an inverted pyramid, the energy of the earthquake wave is proceeding along the side surface of the antiseismic body to the ground and is decreasing progressively, so that it is released to the outside of the periphery of the antiseismic body effectively. So the fracture or the overmuch motion of the conventional base body because the earthquake wave directly contact to a large bottom surface of the base body will not happen. Also, the friction between the antiseismic body and the stratum increases, and the ability of the antiseismic body to bear the load and the stress resulted form the load raises. When the soil is liquefied, the antiseismic supporting base body is possibly to sink but hardly to collapse.

(2) Because the strongest antiseismic strength of the antiseismic body of the antiseismic supporting base body is located in the central axis of the antiseismic body, the centre of gravity of the building can be set in higher position moderately, especially in the tower-style building. In the condition that using the same quality or the same quantity construction material, the antiseismic supporting base body in this present disclosure is better in some performances such as the stability, the antiseismic ability, and the storm-proof ability.

(3) By using the soil nail or the anchor pole, the supporting efficiency of the antiseismic supporting base body increases. The soil nail or the anchor pole is suitable used in the area where the earthquake happens often or the water level of the groundwater is lower, or in the natural foundation.

(4) The antiseismic supporting base body can be considered as an assembly unit and be extended by a plurality of the assembly unit so as to become a structure of which antiseismic strength is better to satisfy the requirement for the building of which antiseismic strength must be higher.

(5) An ancillary bearing is provided at one or more positions selected from a group including the bottom of the main pile, the bottom of the subsidiary pile, and the bottom of the ancillary pile, wherein the shape of the ancillary bearing is similar to an inverted cone or to an inverted pyramid. It increases the friction between the antiseismic body and the stratum and also increases the ability of the antiseismic body to bear the load and the stress resulted form the load.
